CHAMBER-VESS EL. ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 582,247, dated May 11,1897.

Application filed October 8, 1896. Serial No. 608,246. (No model.)

To aZZ whom it may cancer/t:

Be it known that we, WVALTER H. XVESTON and GRACE M. G. WEsToN, citizensof the United States, residing in Vinthrop, in the county of Suffolk andState of Massachusetts, have invented a new and Improved Chamber- VesselAttachment, of which the following is a specification.

This improvement relates to that class of chamber-vessel attachments towhich the invention belongs which is illustrated and de scribed inLetters Patent of the United States No. 541,219, issued June 18, 1895,and it is intended to be an improvement on or over said invention.

The presentinven tion relates principally to the peculiar constructionby means of which the attachment or supporting-frame is attached to,supports, and is detached from the vessel, and the adjustablearrangement for supporting the back.

The nature of the improvement in detail is fully described below andillustrated in the accompanying drawings, in which Figure 1 is aperspective View of our device with the back support or rest raised andin position for use. Fig. 2 is a central vertical section with theback-support lowered. Fig. 3 is a plan View of the under side.

In all three figures the chamber vessel is in position, and in themsimilar letters of reference indicate corresponding parts.

Arepresents the chamber vessel,constructed, preferably, of some lightmaterial, such as wood fiber, papier-mach, or suitably-protected metal,and B is the handle, preferably of metal, and secured to the vessel byrivets or screws or other suitable means at b. The handle is formed upat its upper portion into the substantially flat horizontal portion B,such portion being nearly as high as the up per edge of the vessel.

0 is a circular frame or support made, preferably, of the same materialas the vessel and provided with the inward flange or top 0, formed withthe central opening 0. I Secured upon this top 0 and of similar shapethereto is a base D,.which supports an annular cushion, of which E isthe stuffing and E the cover or outside, the latter secured at itsopposite edges at e and e to the outer edge of the base D and inner edgeof the top 0, respectively. Secured at F to the under side of the top 0is a curved metal supporting-plate F. This plate extends downward on aninward incline for perhaps one-fourth to one-third of the distancearound the opening 0, and is set at such an incline and in such aposition as to extend down along the upper outwardly-flaring portion ofthe vessel, as shown in Figs. 2 and On the opposite side of the openingC there is secured to the under side of the top 0 a spring-plateconsisting of the portion H, which is secured to said top 0, and thehorizontal portion H, which drops, as shown in Fig. 2.

\Vhen the vessel is in position, it is supported on opposite sides bythe spring-plate H H and the curved plate F, the latter lying under theflaring top of the body of the vessel and the former extending under theupper portion 1) of the handle B. To remove the vessel, turn it untilthe plate H H is withdrawn from the handle. To replace it, lay theflaring portion against the plate F-and turn the vessel until the part Bof the handle is beneath the plate H.

In order to support the back of the child or other person using thedevice, the Wire-support K is provided, said support being curved intothe form shown and having it ends pivotally secured to the oppositesides of the frame 0. This support is held in the position indicated inFig. 1 by means of the upright wire L, whose upper end is bent at L intoa loop adapted to spring over the Wire K and whose lower end is loopedat L and thereby swung from a pin or bolt P, extending radially from theframe 0. When the back is to be used, the Wires K and L are swung up andthe latter sprung over the former, as shown in Fig. 1. Reversing theoperation brings the wires into the position shown in Fig. 2.

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent, is-

In a device of the character described, the supporting-frame 0 providedwith the opening C; the inwardly-inclined downwardlyextending curvedplate F secured to the under side of the top 0 of the frame on one sidethe portion H of the plate H, substantially as of said opening; theplate H secured to the described.

under side of said top near the opening and WALTER H. WESTON.

provided with the substantially horizontal GRACE M. G. VESTON. 5 droppedportion H; the vessel A having a lVitnesses:

to said vessel and of shape to be slipped over O. G. GRAYDON.
